Music that sounds familiar

[Moonleg]

So, there are now three pieces of music in the game that seem oddly familiar to me without being able to pinpoint what they remind me of, so I was hoping some of you guys might be able to help me out.

First of all, the piano we can put in our (FC) houses; when clicked it plays a short tune that I'm certain I have heard elsewhere.

The gryphon/airship (and probably others) music. This one reminds me of the N64 days, which is odd seeing as Square made stuff for Sony then rather than Nintendo. I'm reminded slightly of Wave Race 64 or something similar to it.

Matoya's Cave. This one DEFINITELY reminds me of something, I keep expecting someone to start singing. A pop song, perhaps?

Piano is Haukke Manor normal mode's intro

Matoya's cave is a remake of the same place in FF1

Every once in a while I hear a ibt of music that reminds me of the tv series 24. It's just a few bars but it's similar to music they played during the show. Just me I'm sure, lol.

The pillars sounds like a reworked version of the a track from Summoner: A Godess Reborn.

[Evangela]

I think the field theme of Azys Ila sounds like a theme for Mega Man X games.

[DoctaruRavenbe]

I think the field theme of Azys Ila sounds like a theme for Mega Man X games.

I'd need to hear both against each other but I have a feeling Azys Lla's theme is a rearrangement of the FF6 Floating Continent theme

Dusk Vigil's Theme sounds straight out of FFXI's CoP.

Battle Theme in general fighting mobs in HW. I'm always reminded of Kingdom Hearts.

[KylePearlsand]

I can swear to everyone that Qarn hard mode's theme reminds me of a song from Final Fantasy XII but I for the life of me I can't remember the name of the track.

For some weird reason a part of The Great Gubal Library reminds me of a sonic tune >_>
